Dave - when they found out it wasn't a navigation tool or a megasquirt controller I bet they were PO'd. Serves them right.

My '97 Civic had problems where ScanGauge would lose its data. Don't know if your problems are in any way related. But read below; it took me many months to debug this for my car.

Learn what "Mode" you SG has to be in - ISO, CAN, etc. - for your car.
You can set the Mode on SG; explore "More" and/or "Setup" to find it.
- - (Normally it finds the right mode automatically)
Then see if it's lost that setting when it fouls itself up.
My car's issues came down to, I had to put the horn and headlights on relays. I know it sounds weird but switching hi/low and blowing the horn would cause the SG to mess up. It looks like the 12V power through the OBDII connector wasn't stable at those times. Powering those loads separately + directly off the battery via relays cleaned up the 12V power thru the OBDII connector. No more problems, and it's been many months now.
